A characterization of spaces of homogeneous type induced by continuous ellipsoid covers of $\mathbb R^n$

We study the relationship between the concept of a continuous ellipsoid $Θ$ cover of $\mathbb{R}^n$, which was introduced by Dahmen, Dekel, and Petrushev, and the space of homogeneous type induced by $Θ$. We characterize the class of quasi-distances on $\mathbb{R}^n$ (up to equivalence) which correspond to continuous ellipsoid covers. This places firmly continuous ellipsoid covers as a subclass of spaces of homogeneous type on $\mathbb{R}^n$ satisfying quasi-convexity and $1$-Ahlfors-regularity.
